CAR-TRUCK;

SPECIFICATION forming part o' Letters Patent No. 658,390, 'datedseptember' 25, 190C.

Application led January 8, 1900. Serial No. '701.` kNo model.)

To all whom, it may concer-rt:

Be it known that I, EDWIN G. NICEWANER, of Johnstown, in the county ofCambria and State of Pennsylvania, have invented new and usefulImprovements in Car-Trucks, of which the following is a full, clear, andexact description, reference being had to the accompanying drawings,which form a part of this speciiication.

My invention has relation to certain new and useful improvements incar-trucks, and more particularly to the arrangement of the axle orjournal box springs.

It is often desirable in car construction to reduce to a minimum thevertical distance between the underside of the car-body or its sills andtrack or road-bed, and in such cases l it is a matter of some difficultyto provide sufficient space for the journal-box springs, which areusually seated upon the journalboxes and between the same and suitablebearings on the vehicle-body or on the truckframe for the purpose ofcushioning or relieving upthrusts of the axles due to trackirregularities, obstructions, &c.

The object of my invention is therefore to provide for seating thesesprings in a Inanner which will enable them to be utilized to their fullextent without using therefor any of the space between the journal-boxesand the bottom of the car-body, so that said carbody and sills may bebrought nearer to the tops of said boxes.

With this object in viewmyinvention consists in seating the journal-boxsprings laterally of the journal-boxes and in so connecting them withthe said boxes that they receive by compression upward thrusts ormovements of the boxes and also the weight of the load, and thus relieveor cushion the effects thereof.

The invention also consists in the novel construction and combination ofparts, all as hereinafter described, and pointed out in the appendedclaims, reference being had to the accompanying drawings, in which-Figure l is a side elevation of a portion of a car-truck, partly brokenaway, having my invention applied thereto. Fig. 2 is a side view of oneof the journal-boxes. Fig. 3 is a side view similar to Fig. 1, butshowing a modiiied form of the invention; and Fig. 4 is a detail view.

The letterA designates the side frame of a car-truck, and B one of thepedestals or journal-box guides. B' isa journal-box mounted in Saidguides. C C are two helical springs, seated one at each side of the saidguides.

D D are two levers, one of which is pivoted to a lug c of each of theguides, it-sinner arm being formed into a toothed segment whose teethmesh With rack-teeth E, formed on the side of the journal-box B. Theouter arm of each lever is pivoted to a cap F, resting on the adjacentspring C. The toothed arm of the lever extends through an opening binthe side of the journal-box guide.

The operation will be readily seen. The load of the car, transmitted tothe side frames through the usual car-springs, (not shown,) is carriedonto the journal-boxes'and axles through the levers D, which are movedunder the load to compress the springs C, which thereby relieve theteeth of the dead-weight of the load. Any npthrust on the journalboxes,due to high rail-joints or other causes, is relieved by the springs C bycompressive action thereon.

In the modification shown in Fig. 3 springs C are seated in pockets H,cored in the bottom of pedestals or guides B, and instead of employingthe segment-levers D,I provide the spring-caps I with upward barextensions K within the said guides. These extensions are formed withrack-teeth K', which are engaged by the teeth of the pinions M, journaled in the guide and meshing at its Opposite side into therack-teeth E of the journal-box. The lower ends of the spring-pockets Hare closed by removable caps H,bolted thereto and seating the springs.The operation is substantial] y the same as in the form iirst described,rotation of the pinions M, under either downward movement of thecar-frame or upward thrust of the journal-boxes, eecting a compressionof the springs C'.

I do not wish to limit myself to the particular embodiments of myinvention which I have herein shown and described, as othermodifications, together with various changes IOO Having thus describedmy invention, what I claim, and desire to secure by Letters Patent, isf 1. In a car-truck, the combination w`ith a truckframe havingjournal-box guides, journal-boxes mounted in said guides, journalboxsprings seated in their lower ends on the said frame laterally of theboxes, and connections between said boxes and the upper ends of saidsprings whereby the latter are cornpressed by up thrusts or movements ofthe said boxes.

2. In a cartruck, the combination of a truck-frame having journal-boxguides, and journal boxes mounted in said guides, of springs seated onsaid frame laterally of said boxes, and gear connections between thenpper bearings of the said springs and the said boxes.

3. In a car-truck, the combination with a truck-frame and a j ournal-boxmounted therein, of springs seated laterally of said box, andconnections between the box and the upper bearings of springs wherebythe latter are compressed by the load on said frame and also by upthrusts or movements of said box.

4. In a car-truck, the combination with a truck-frame, havingjournal-box guides, and journal-boxes mounted in said guides, of helicaljournal-box springsseated on said frame laterally of the boxes, andhaving movable upper hearings or caps, and gear connections between thesaid bearings and caps and the journal-boxes.

5. In a car-truck, the combination with a truck-frame having journal-boxguides, and a journal-box in said guides, of aspring seated on saidframe at each side of the said box, and having movable upper bearings orcaps, and gear connections between the said box and the respectivesprings.

6. In a car-truck, the combination with a truck-frame having journal-boxguides and a journal-box therein, provided with r'ackteeth at oppositesides, of a helical spring seated on the frame at each side of saidguides, movable upper bearings 0r caps for said springs, and leverspivoted to the said guides and each having one arm pivoted to the adjacent upper bearing or cap, and the other arm provided with a toothedsegment which engages the rack-teeth on said box, substantially asdescribed.-

7. In a car-truck, a journal-box having rack-teeth formed at oppositesides thereof, journal-box springs seated on the truck-frame laterallyof said box, and devices engaging said rack-teeth and arranged tocompress said springs under the load 0n the truck and also underupthrusts of said box.

In testimony whereof I have affixed mysignature in presence of twowitnesses.
